Rektash said:I played through the game three times with a 135h melee character too, and I found this helps a great deal to pretty much perfect backstabs. I made my Plat with this character. Test it for yourself and see how well it works.
Could just be that you're both right, and the real trick to perfecting backstabs is to stop strafing left/right once you get behind the enemy. Whether that means leaving the analog stick on neutral for a split second or pushing forward, either way gets you to stop strafing.
